eater confined to Kauai. There are three species of fly-catchers, 

 all entirely insectivorous and very beneficial. 



Exhibitions and Notes. 



Mr. Swezey exhibited specimens of Dacus cucurhitae which he 

 had bred from string- beans ; he also showed a red Tortrix, name 

 unknown, but identical with the one bred by Mr. Wilder from 

 lichee nuts and exhibited at the previous meeting. This moth 

 Mr. Swezey has also bred from the pulp of mango. Mr. Swezey 

 also presented interesting- notes on the habits of Calliiieda tcstudi- 

 naria, since published in the Bull. H. S. P. A. Ent. I, pp. 224-8, 

 PI. XV., figs. 1-4. 



Referring to Dacus cucurhitae, Air. Craw stated that he had 

 also observed this insect at work upon beans, and Mr. Perkins 

 stated that Mr. Van Dine in his 1904 annual report refers to this 

 same insect observed on the same plant. Mr. Kotinsky wondered 

 at the possibility of raising melons or cucumbers anywhere on 

 these islands in view of the unchecked presence of this fruit fly. 

 To inquiries for remedies against this pest he always replied sug- 

 gesting clean culture, destruction of infected parts and liberal feed- 

 ing of the plants liable to injury by this insect. Mr. Weinrich 

 stated that he had experimented with a tenth of an acre plot of 

 melons. He covered some of the fruit as soon as it set, but after- 

 ward found that while some of the covered melons were stung, 

 many of those uncovered were unstung. He suggested the possi- 

 bility of raising melons on the windward side of this island by the 

 prevalence of strong winds which drive the fly away. His experi- 

 ment with raising musk melons was a total failure ; one of these 

 fruits showed absolutely no traces of the fly sting but was, how- 

 ever, full of the maggots when cut open. These maggots were 

 small, and Mr. Swezey offered the suggestion that the puncture 

 might have been a very recent one, which would account for the 

 difficulty of discovering it. Mr." Austin stated that he saw musk 

 melons that were raised near Diamond Head. The fly, he said, 

 attacks the vine as well as the fruit of melons and cucumbers. 

 Mr. Perkins also referred to an observation he made on wild figs 

 in Australia, which he found so full of fruit fly maggots that they 

 could not reach maturity. Mr. Terry stated that he observed at 

 Kaimuki a kind of cucumber grown by the Chinese. To 

 protect these from the ravages of the fly these people usually
